This bill, known as the "No Tax Breaks for Sanctuary Cities Act," aims to amend the Internal Revenue Code of 1986 by denying tax-exempt status for bonds issued by jurisdictions designated as "sanctuary jurisdictions." This change would mean that interest earned on bonds from these entities would no longer be exempt from federal income tax, potentially increasing their borrowing costs. A "sanctuary jurisdiction" is defined as a state or political subdivision that has a policy or practice prohibiting or restricting government entities from sharing immigration status information with other government bodies. It also includes jurisdictions that fail to comply with lawful requests from the Department of Homeland Security for detainers or notifications regarding the release of individuals under the Immigration and Nationality Act. To implement this, the Secretary of the Treasury, in consultation with the Secretary of Homeland Security, would be mandated to publish an annual list of these jurisdictions.
